Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552764, here are decompositions:

17 + 31552747 = 31552764
31 + 31552733 = 31552764
37 + 31552727 = 31552764
43 + 31552721 = 31552764
71 + 31552693 = 31552764
83 + 31552681 = 31552764
211 + 31552553 = 31552764
227 + 31552537 = 31552764

Showing the first eight; more decompositions exist.
